To all whom it may canoe m Be it known that. I, Riormno C- C{)NGY)ULW, a. citizen of the United States, and a, resilient of Atlanta. in the county of Fulton and Stole of Georgie, have invented certain new and useful Improve neihis in Apparatus for the lllanufacture k .,ool-ilns, oi which 'lhe following is a, specification.

The principa objects of the present invention are to prevent the nccnmulz'uiion of tar, pitch and lamp black inside the shuul pipe; to scrub the gas in the sifiml pipe and thus lessen the burden on the balance of the Works; to increase the capacity of the boosters, condensers and scrubbers; to rapidly cool the gas inside the stand pipe; "to provide for zliseshiblishing communication between the stand pipe and any retort or reliorts, While the some is being charged or drawn, by means of a valve or valves which remain clean and operative;,to oh viote the expense, annoyance and work of cleaning the stand pipe at frequent intervals by manual or mechanical means. and to reduce the firsljcosholi the installation While attaining the ocivontages above, reoiteol.

Broadly speaking and Wihhoutdisclaimi11g any novel features of the invention. the above objects are accomplished by the Clown- Word circulation of Water, water gas huor other fluid insiole the stanti pipe but; will:- out getting it. inside the retort or rotorls connectecl to the stand pipe in combination with the ascension of the gas through the slzuul pipe and with the nn'angement of valves in side the stand. pipe, so that 'iziicy are kept clean by the descending fluid.

The invention will he claimed at he end hereof, but will be first described in cow neoiion with the embodiment of it chosen, from among other embodiments, for illusiration in the oocompmiying drawings, in Which Figure 1, is a front view With ports broken away and partly diagrammutically illusirzitingg one form of apparatus embodying fQili'lll'Gi-l of the inventions Fig. 2, is :1 sectionol view taken on the line 2-f2 of Fig. 1 and drawn to an ()l'llfllgECl scale. Fig. 3. a front View, with parts broken away, of another fol-1n of apparatus emluulyiug u modifimtion of the invention, and Fig. i, is a side view with ports broken mvay of the apparatus shown in Fig. 3.

In the drawings 1, are the relorls of an oppurulus for the muuulj'orl'ure of (foul gas.

The reloris coumuuiicul'e pub the stand pipe by moons of branch pipes 23 iiluure are means for (l. ohurgiug lllllil or liquid, such as water, W5. mi? or other fluid. preferably in a li- \uleil sluie lilac. spray. (lmYmVurd il'u'ough the stand pipe. ll'iihiu the slnnrl pipe there. are valves for establishing and (liswssl'nblishinn" connnuuicnlion bol'weeu the interior of the relorts and the stand pipe. The (losmindiug liquid or fluid performs several important fuilcl'ious. it keeps the stand pipe clean. which a matter of lhe utmost importance and value as will be understood by those skilled in the art; it scrubs and cools the ascending gas so that the rest the appnrzu'us, not shown. is relieved of (his work, thus iucrousiun' the vu mritvof the plant lllNl reducing the first cost of installation, and ii; keeps the valves clean so that. they man be readily operated when it is necessary or desirable to establish or dis-establish cominuniration hehvocn tho relorl's, or any of them. mul the stand pipe. After descending lhrougli the stmul pipe Hie liquid or lluicl is oolleciml in a (rough or the like l. into which 1.110 lo\\'0l' culls of the stand pipes (lip so that the wrupe l. nus ul' lheir lower umls is sealed oll mul prm'culed. iii. the top of The stand pipes (be our only be loll. oil directly iniio uu olllulw pipe or collwa'l'iug main 5', (Fig. 2%) or it may be led oil through a wash bow, or soul o (Fizz: l).

As shown in Fig. 3, lhe valved pipe lel;

(llSClllllfJ'OS inlo the, top of the stand pipe, for example, against a bulllo plate 15 umi so the. spray or downward circulni'ion through he slam! pipe above referred to is accomplished. The valves which are or- 2 lessees ranged in the stand pipe may beer" any variety. As shown in Fig. 1, these valves are of the flap variety and are all alike so that a description will be given of one of them. The valve-16 mounted upon one arm 17 of a rock-shaft 18 arranged"within the stand pipe and the other arm 1 9 is ar ranged on the rock-shaft 18 but outside of the stand p pe so that it isaocessible from the outside. 20 is a'la-tch pivoted to a suitable bracket and adapted to he turned down over the arm 19-. so .ss to hold the Valve 16 in closed position and who turned up clear of the arm 19 so as to permit the valve 16 to he opened. I

The valves shown in Figs. i and 3 are arranged inside of the stand pipe and they are all alike so that a description of one is suflicient. These valves 21 are slide valves provided with handles 22 which extend through the wall of the stand pipe and they are slid in and 613.1580 as to cover and on cover the opening in the branch pipe 3. Of course, suit-able stufiing boxes, or the like, may be provided to prevent leakage at the points where the operating handles of the valves pass through the wall of the stand pipe and the various parts may he made of metal or other appropriate material.

It will be obvious to those skilled in the art to which the invention relates that modifrom the spirit or the invention since the latter is not limited in regard to such mattors.

What I claim is:

1. In apparatus for the manufacture oi coal gas the combination of a retort, a stand pipe in communication with and extending above and 'helow the retort, a valve arranged in the stand pipe for establishing and dis-establishing communication between the stand pipe and retort means for Withdrawing gas from the retort upward through the stand pipe, and means for supplying liquid dovvnward through the stand pipe onto said valve and past the retort.

2. In apparatus for the manufacture of coal gas the combination of a stand pipe, a retort, a valve located in the stand-pipe for establishing and dis-establishing communication between the stand pipe and re tort, and means for introducing liquid down the stand pipe onto the valveto keep it clean, substantially as described. 7

In testimony whereof I have hereunto signed my name.
